Ghosts of the Future: First Giant Structures of the Universe Hold 800 Trillion Suns – Astronomers using the South Pole Telescope report that they have discovered the most massive galaxy cluster yet seen at a distance of 7 billion light-years. The cluster (designated SPT-CL J0546-5345) weighs in at around 800 trillion Suns, and holds hundreds of galaxies. –Science Daily

Confirmed Exoplanets Could Reach 500 by the End of This Month – If it seems like a new extrasolar planet is discovered every week these days, that’s because there is. In fact, the rate is actually faster than one per week – 70 have been discovered thus far this year alone, bringing the overall tally of confirmed exoplanets at 494. At that pace we very well might hit exoplanet number 500 before the end of this month. -Clay Dillow / PopSci

Being in space can change the way you view the Earth – That was certainly the case for the Apollo 8 crew who produced the iconic image of our planet emerging from behind the limb of the Moon –Jonathan Amos / BBC

Hubble and Rosetta unmask nature of recent asteroid wreck – High-resolution images from the Hubble Space Telescope and a rare view obtained, from a unique perspective, by the Rosetta spacecraft provide a comprehensive picture of P/2010 A2, a puzzling body in the asteroid main belt. –ESA

Win a trip to ESO’s Very Large Telescope (VLT) in the new ESO Hidden Treasure contest – a free competition for everyone who enjoys making beautiful images of the night sky using real astronomical data. The competition has some extremely attractive prizes for the lucky winners who produce the most beautiful and original images, including an all expenses paid trip to ESO’s Very Large Telescope (VLT) on Cerro Paranal, in Chile, the world’s most advanced optical telescope. –ESO Observatory

ISS Instrument Detects X-ray Nova – An instrument on board the International Space Station has discovered an X-ray nova. The science team from the Monitor of All-sky X-ray Image (MAXI) instrument on the Exposed Facility of the Japanese Kibo reported a short-lived X-ray nova became visible in the constellation of Ophiuchus on September 25, 2010, and the MAXI team confirmed that it was an uncatalogued X-ray source. –Nancy Atkinson / Universe Today

Starry Sky Tonight

January 26, 2010 21:34 by scibuff

It was a very cold day in Amsterdam today but along with it came virtually cloudless sky, so I had the chance to continue taking photos of the Moon as it approaches the Full Moon (06:18 GMT on January 30) as well as the perigee (09:04 GMT on January 30, 2010) when the it will be 356,592 km away from the Earth – the closest this year.

(Compare the Moon with photos from January 25 and January 20)

My next target was the open cluster Pleiades (M45). The effects of close proximity with the Moon tonight is visible on the left side of the photo.

Finally, I turned the camera towards the constellation of Orion and one of the most scrutinized and photographed objects in the night sky – The Orion Nebula (M42).
